My first tests were weighed with an inexpensive .01 gradient scale.

My later results to the .001 digit were weighed with an inexpensive .001 gradient scale.

The results from jackgastche were weighed with a .001 gradient scale, but rounded off to the .01 digit.

How to do the test,

Cheapest generic supermarket one gallon ziplock bag, cut the ziplock off, fold up, place on .01 or .001 scale, record tare weight, fold over the top one inch to the outside, place in a pyrex dish, place the pyrex dish in another dish, squirt a full can of ~300ml butane lighter refill into a quart Mason jar as per the video, pour the liquid butane into the plastic bag, add warm water to the larger dish, after boil off vacuum purge the bag, fold the bag, place on scale, record weight, deduct tare weight from final weight, post result to ICMAG's "Butane Residue Test Results" thread. TIA!!!

Freeze the can of butane and the Mason jar by placing in the freezer for a couple of hours before the test to maximize the amount of liquid butane collected.

1.25 watt per square inch Briskheat silicone heater dimmed with a lamp dimmer so the exposed to ambient areas of the mat max at about 170F. You burn the mat out, you're very likely toast! The blue work mat is a grounded, three layer, ESD, anti-static mat.

Could you do a couple runs of the procedure on empty bags without any butane, just to find what the weight of a blank would be? The above procedure has you handling the bag a number of times after taking the tare weight. That makes me wonder how much of the values you got (for the butane runs, above) were weights introduced during the handling of the bags (i.e. skin oils, fats, mayonnaise, cheeto dust, etc. that does not volatilize off under vacuum) One cannot assume that a blank is zero, and blanks seldom are.

Sanitary handling procedures were followed. Contamination isn't an issue. I did check a couple of things, an unused bag weighs the same before and after vacuum, and vacuum purging the bag after the butane boil off is necessary. I record ten to twenty or so readings of the tare and final weight with calibration every five or so readings, gives the scale a chance to warm up and stabilize.

Some of the readings in the 0.001g zone are probably indeed less, running multiple cans and dividing the result by the number of cans is a solution to the scale resolution error, but I don't see the need at this time.

I have Xicar, Power 0X, Iolite, and Lotus on their way to me for testing.

I'd appreciate it if someone with bulk butane would run the test with a cans' worth of butane. A 300ml can of butane fills a Ball wide mouth quart Mason jar with about 225-250ml of liquid butane going by the volume markings on the side of the jar. The test is simple, doing it carefully takes time.

thanks for all the time effort and mola invested, great job

Cant wait to see peoples reaction when they learn zippo is cleaner then vector!!

I actually have the bulk butane ready for testing, but lost my testing resource, so will have to punt.

I found a a lighter weight ASME pressure pressure bottle for a transfer container, so I can more accurately measure the amount decanted from the Lp-5, but need to make a more suitable lid for it.

Just dumping the butane into a chilled jar to the measured line would certainly be simpler, and probably accurate enough.

Please explain what you mean by sanitary. It has nothing to do with running a blank, but I'm curious what you meant by sanitary.

That's nowhere near the same as running a bag through the whole process, including boiling the bag about the same amount of time as you did the actual samples.

I agree. But doing it right means taking the time to do blanks.

When you're looking for trace things, you have to run blanks because it might be what you see with your samples is actually a variability within the process itself. You cannot reason it away, you can only run blanks and report the values. That is, if you want to do it right. I take it you didn't do that, and that's why I asked you to run some blanks.

Thanks.

I already have test results below threshold (<0.001g,) think about it, that should answer your question. I'm not getting readable contamination.

Sanitary means that the entire test was conducted in a dust and bug free area, and that all surfaces, including my hands are clean at all times. Sanitary, as in "clean room" from the electronics and aerospace industries.

That doesn't matter. It's not about the lowest reading you get, but the significance of the all the readings you get. Since you cannot understand that, you want to try to reason away the necessity of running blanks.

Suppose you run blanks and find that they produce readings that are similar to the ones you claim were actual values. Subtracting out the blank you might find that all your readings were below threshold. Since you didn't run any blanks that question remains, and it's a fairly large one.

I doubt you have all the air HEPA-filtered, which "clean rooms" routinely do. That you didn't wear gloves when handling the bags is an identified source of error.

No analytical chemist would touch something that they are weighing down to the milligram. None. Never. Ever. So when you do that the need to find out what you introduced when handling them is very strong, and blanks address that.

I'm not running a faux test just for you when actual tests results are already beneath the threshold of the scale, i'm sorry to repeat myself, but that's the answer. It takes ALOT of visible dust and/or skin oil to throw a reading off by a milligram, and it's simply not occurring.

Why not try a residual test yourself?

I can't believe people smoke BHO. That's all I'm saying.

I flash vaporize, lately at about 710F. Smoke, containing soot comes from lesser concentrates like bubble hash in my experience. Here's a picture of the piece of glass I use to inhale BHO vapors with about a week's worth of claim build up, notice no soot.

Iolite had 0.010g of residue

Iolite, England, 300ml can, reads on the bottom "DOM 30.07.13 22:45"


The results will be added to the first post in this thread,


So, not all the English/UK butane is the same.

Btw, the notes at the bottom of the test result page are necessary to fathom the numbers. I included the early test results done with the .01 gradient scale out of inclusiveness, same goes for the other guy's results. You need to compare apples to apples, only use my results that are expressed out to milligrams (.001g.)

Ordered the new Vector 14X and some Clipper.

I am open to suggestions of what to test.

do the clipper 12-loop refine isobutane. I'd like to see this one tested

I'll update the beginning results post.

I ordered a case of the new N-Butane canned extraction solvent from CapitalButane.com, test results asap.

Thanks for posting these SkyHigh. I picked up a few samples recently to try and figure out which one I'd like to use. Here's what I found:

Power

Fasfil

Newport


All are depositing what are most likely paraffins but only Newport had a clean smell. It appeared that there was slightly less material on the mirror as well but this is just a 5 second spray and not precisely conclusive. The lack of the smell in the newport is the most important thing to me. It is double the ticket/can though.

you didn't spray that inside did you? from your surroundings it appears to be a stationary mirror.
